Abstract :
Magnetization and torque measurements were carried out for Nd2Fe14B and Ho2Fe14B, and yielded similar results for the spin reorientation temperature (135 K and 133 K, respectively), and for the angle of inclination of the easy magnetization axis from the c axis (30. 3-30. 7° at 4.2 K, 26.5-26. 9° at 77.3 K). The anisotropy-constants K1 and K2-K3 were determined from approximations of torque curves for the Is angle.
